Characteristics of GOHSENOL™

Gas Impermeability

GOHSENOL™ films formed either independently or on other materials such as paper show very high impermeability to many kinds of gases such as oxygen, nitrogen, hydrogen, carbon dioxide, and helium ; however, moisture and ammonia can permeate the films.
